"0 all w7wm i/; may concern:

Be it known hat I, ELWOOD CHAPMAN, a citizen of the United States, residing at C011 stant, in the county of Oowley and State of Kansas, have in vented a new and useful D001- Cheek, of which the following is a specificati0n.

This invention has relation to improvements in door-stops; and the objeets in view me to provide nn extremely eheap and simple stop adap'ed t0 automatieally check and accidentai siamming, said stop to be so constrncted as to be ieadily diseonneeted and liberate the (1001 by an application of the toe of the boot of the operator.

1Vith the abox*e and other objects in view the invention consists in ce1t-ain features of eonstrnetion hereinafter speeified, and pertieularly pointed out in the claim.

leferring to the drawings, Figme 1 is a general view of my invention applied to & d0or and mopboaid. Fig. 2 is en e1arged detail in longitudinal vertical seetion, the stop being in EL loeked position. Fig. 3 is L detail in perspeetive of the housing.

Like nnnnerals indicate 1ike puts in a1l th'e figures of the drawings.

'lhe stop, as is usnal, eomprises two membe1s, 0ne being designed for application to 1he door and the other to the mop-board or other eonvenient point opposite that point of the door at Whi0h the eompanon member is located. The 1nember located upon the mopboznd consists of a baseplite 1, having screwopenings 2, tinough whieh cue passed serews 3 into said mep-board. Fornned integral with the p1aie 1 is an 0b10n g housing 4:, made 1101- 10W and hzwiug the front porti0n of its 10We1 wa1l and the lower p01tion of its front wa1l provided with a slot 01 opening 5, the lower slot being crossed by 1 tmnsverse bar 6.

7 designates & latch pivoted in the. 1ea1 end of the honsing by a hearing-pin 8, said 1ateh beeing f1ee f01 vertieal vibrations within the, honsing and normaliy resting I1ea1 its front end npon the stop-pin 6. 1Between its ph0t and the pin 0 the lateh is provided with a depending iug 9, the lower end of whieh is beiow the housing, as shown. '1he free end of the 1atch is provided With a depending h ead 10, the innei 01 rear edge of whch is provided with a trensverse 1ib 11. The opposite men1ber, 01 chat secured to the door, consists of a base-plate 12, hzwing perfora tiens 13 for the reeeption of serews 14, whieh letter pass into the (1001, and said piate has f0rmed inegral therewith a laterally-disposed L-shaped 1ug 15, the upper inner edge of Whieh is provided With the I'b 16, similar to the rib 11 of ;he 1ateh 7.

In operatien the door is swnng toward the mop-board nntil the upper edge of the L- shaped 1ug 15 abuis ageinst the beveled face 17 of the head 10 of the latch 7, whieh eanses said latch 7 te rise and drop over the said L-shaped 1ug, whereby the door is locked in the open position and eannot be inflneneed to be aceidentally elosed by the wind 01 ether ordinary eauses. T0 release the door in 01- der t0 close it, it is neeessary to press the same slightly to the rem 01 toward the mop board in order that the 1ibs 11 and 16 wi1i be thrown out of aiignment and their intei" loeked position, when by applying the we of the boot to the 1ng 9 said ]ateh may be ele vated and the L-shaped 111g liberated, whereupon the door may be closed. It is apparentthat acciderita1 knoeks given the 1ateh or attempts of small ehildren t0 disconneet the door wil1 11013 aecomplish the same, fox the reason that, as before stated, in order to accomplish such disconneetion the door must first be pressed toward the mop-board,- and thus disconneet the interloeking 1ibs 11. and 16, 01 rather throw them out of alignment.

Having deseribed my invention, what I claim is= In a door-stop, the opposite members adapt ed to be applied to the door and mop-board, 011e member eonsisting of a base-plare per fomted for the reeeption of: screws and hav ing an integra1 latemily-disposed housing siotted upon its under side and at its end, ZL lateh pivoted at its rem end in the housing and havng; its f ro nb end p10 j ecting through the slot in the front end of the housing and provided with a depending head, the rem
